Affect of direction of a bond relative to other bonds on bond length

[Kailey Nichols 4B]

Does the direction of a bond relative to other bonds in a molecule affect how long it is? For example, are the single bonds in a molecule like tetraphosphorus (P₄), which has a tetrahedral structure, shorter than a molecule with only one single bond?

I know that the shape influences the bond angle but I don't think it influences the bond length. I think only things like the identity of the atoms being bonded and the number of electrons being shared would affect the bond length.
